The below is not working. Trying to check the duplicates in the lookup file before entering the user parameters 
if(check_dup_rec("$APPHOME/DATA/lookup/lookup_file.txt","$actv_id,$ite
+ration_id,$wave_id"))
     { print "\nTo ABORT press CTRL+C or Press ENTER key to Continue..
+.";
       chomp($key = <STDIN>);
     }

  check_dup_rec("$APPHOME/DATA/lookup/lookup_file.txt","$actv_id,$iter
+ation_id,$wave_id");
